What material are car horns made of
The materials for car horns are diverse. Common ones include steel (such as chromium-vanadium alloy steel), aluminum alloy, ductile iron (such as QT400-15), titanium alloy, and composite materials (such as carbon fiber). The specific material selection depends on the vehicle model positioning, cost budget, and performance requirements.
Youdaoplaceholder0 Mainstream materials and their characteristics
Youdaoplaceholder0 steel .
Youdaoplaceholder0 chromium-vanadium alloy steel : It features high strength, wear resistance and corrosion resistance, and is widely used in ordinary vehicle models, with outstanding cost-effectiveness.
Youdaoplaceholder0 carbon steel/alloy steel : By adding alloying elements, its hardness and wear resistance are enhanced, making it suitable for vehicles with high durability requirements.
Youdaoplaceholder0 aluminium alloy .
The advantages of lightweighting are significant and it is mostly used in high-performance or energy-saving models (such as Excelle and Qashqai), which can improve fuel economy and handling, but its strength is slightly lower than that of steel.
Youdaoplaceholder0 ductile iron (QT400-15/QT450) .
The tensile strength is ≥400MPa, and the elongation is 15%, meeting the high-strength requirements. It is commonly found in economy models (such as some Sagitar models).
Youdaoplaceholder0 titanium alloy .
It has excellent lightweight and corrosion resistance, but is costly and mainly used in high-end vehicle models or racing cars.
Youdaoplaceholder0 composite material .
For instance, carbon fiber reinforced plastics are lightweight and corrosion-resistant, but they are expensive and are often seen in the racing field.
The influencing factors of material selection
Youdaoplaceholder0 model positioning : Economy cars mostly use cast iron or steel, while luxury/performance cars tend to use aluminum alloy or titanium alloy.
Youdaoplaceholder0 Cost and performance balance : aluminum alloy is light but has a higher cost, while cast iron offers better value for money but is heavier.
Youdaoplaceholder0 Application environment : In high-temperature and high-humidity areas, the corrosion resistance of the material should be considered (for example, titanium alloy is superior to plastic).
Youdaoplaceholder0 dispute case
Some models of the 2025 Sagitar have been complained about having their aluminum alloy horns downgraded to cast iron, which may affect the suspension response speed and have sparked discussions on material cost reduction.
It transmits and bears the load at the front of the vehicle, supporting the front wheels to rotate around the main pin to achieve steering
The core function of the car knuckle (i.e., steering knuckle) is to transfer and bear the load at the front of the vehicle, support and drive the front wheels to rotate around the main pin to achieve vehicle steering, and at the same time bear the impact load during driving to ensure driving stability and safety. Youdaoplaceholder0, as a key component of the steering system, directly affects the vehicle's handling sensitivity and driving safety.
Youdaoplaceholder0 Core functions are associated with structure
The car knuckle (officially known as the steering knuckle) is the axle head at both ends of the I-beam in the front of the vehicle that undertakes the steering function. It is named so because its shape resembles a goat's horn. Its core functions include:
Youdaoplaceholder0 Load transmission and bearing : Supports the weight of the front part of the vehicle and distributes the power and braking loads to the body structure.
Youdaoplaceholder0 drive steering : Connect the ball pin, tie rod and other components, convert the steering wheel command into the rotation of the front wheels around the main pin, and achieve precise steering.
Youdaoplaceholder0 Shock buffering : Absorb the variable impact loads caused by road bumps, potholes, etc., to reduce the impact on the vehicle body and driving comfort.
Youdaoplaceholder0 Importance and damage effects
The horns of the sheep need to have high strength (usually made of ductile iron) to ensure stability in complex road conditions. Once damaged, it will cause steering failure, vehicle deviation or abnormal wear of the front wheels, seriously threatening driving safety. Its compact and lightweight design strikes a balance between strength and flexibility, making it suitable for all types of vehicles. It is a core component that ensures driving safety and comfort.
